What is a “macronutrient”?

A macronutrient refers to the nutrients that are required by the body in larger quantities for energy and overall health. These typically include carbohydrates, proteins, and fats. Each of these macronutrients plays a critical role in providing the energy required for various bodily functions, supporting growth and development, and maintaining overall health.

Carbohydrates are primarily responsible for providing quick energy, proteins are essential for growth, tissue repair, and the production of enzymes and hormones, while fats are crucial for long-term energy storage, protecting organs, and aiding in the absorption of certain vitamins. The classification as "macro" indicates that these nutrients are needed in significant amounts compared to micronutrients, which include vitamins and minerals that are required in smaller amounts for various physiological functions.
